WILLIAM CHAR/LS BOGENSCHUTZ, OF KALAMAZOO, MICHIGAN, .ASSIGNOR TO KALA- MAZOO STOVE COMPANY, OF KALAMAZOO, MICHIGAN.

FLASK.

To all whom it may concern:

Be itknown that I, Timmer Citanns Boormsouirrz. a citizen oit the United States, residing at Kalamazoo, hlichigan, have .i11- vented certain new and use'tful Improvements in Flasks, oi' which the following is a speci tication.

This invention relates to improvements in 'flasks It relates particularly to an improved hinge tor flasks.

The main object o'tf this :invention is to provide an imln'oved `tlask hinge which permits the swinging' ot' the cope and the removal ot' the match or parting plate with little likelihood oit destroying the mold, and thus facilitating molding' operations.

Further objects, and objects relating` to structural details, will delinit'ely appear from the detailed description to tollow.

I accomiiilish the objects oit my invention by the devices and means (lescribed in the :following specitication.

The invention is clearly detined and pointed out in the claims.

A structure, which is a, pre'tirred embodinient ot my invention, is clearly illustrated in the accompanying drawing. jtorming a part of this speeitication. in which Figure 1 is a detail perspective view ot" a structure embodying the teatures ot' my invention. Fig. 2 is a detail perspective view with the cope in its open position and the match or parting plate removed. Fig, is a detail perspective view of the match or parting plate and its hinge member. Fig. et is a detail vertical section taken longitudinally of my improved hinge. as on a line corresponding to line eiwit of Fig. 5. Fig. 5

a transverse section taken on a line correspendingl to line 5 5 oit Fig. 4.

In the drawing. similar reference characters refer to similar parts throughout the several views, and the sectional views are, taken looking` in the direction ot the little arrows at the ends of the section lines.

Referring t the drawing, 1 represents the drag, 2 the cope and 3 the match or parting plate ot a tlask, the parts being shown largely in conventional form. I provide a draghinge member, consistingI oit an angleshaped body or strap 4t, having an upwardly olii-setl hinge arm 5 thereon. This arm is provided with a pair of knuckle sockets, each consisting of a slot-like central portion` Specification of Letters Patent.

( having downwardl v-converging sides and outwardly-expanding eonically tapered end portions T. The outer socket member is open at the outer end ot the arm, as shown in the drawings.

The match plate hinge member consists oit a body portion S ha ving an upwardly ott`- set; binge arm t) thereon provided with a knuckle comprising a central cylindrical portion having conical sides and out- \\ardl|\\'expauding conical end portions il'l.

The inner socket ot. the drag is preferably open at the. bottom, as shown, to receive the stop lug or rest 'I2 on the lower side ot the central portion '10 o'tl the match plate hinge member. This stop is positioned to engage the rest 13 o't the. drag when the match plate is in its closed position. i

,lhe drag hinge member is provided with a depr seat'. llt adapted to receive the body ot the match plate hinge member when in its` closed position. the match plate being lapped upon and secured to the body oit the parting plate hinge member, as shown in the drawing. Ihis seat is o't such depth that the upper surface ot the body ot the match plate hinge member is in the same plane as the upper surface ot? the remaining portion ot.t the body off the drag hinge member, so that the match plate rests thereon` as shown in the drawing.` it being, however, :further supported by the stop lug 12.

The cope hinge member consists ot an angle-shaped body portion 15, having an upwardly o'tli'wset arm 1G thereon, the arm being provided with a knuckle at its outer end comprising a central portion 17, adapted to coact with the outer socket ott the drag hinge member. At each side of this central portion is a conical end portion 1S. The central portion 17 is provided with a stop lug' 19 adapted to engage the rest Q0 when the cope is in its erected position. By thus shaping the sockets and knuckles, the parts are ettectively guided and centered so that they are automatically brought into proper position in closing the `flask. Further, when it is desired to remove the match plate. the cope is supported in its open position by the stop. as described. The match plate is supported by its stop-lug so that in rapping the plate preparatory to removing it, the mold is notl likely to be injured by the swinging o't the plate.

I have illustrated and described my i1nproveinents in detail in the form in which I have embodied them in practice, and which form I ind to be very satisfactory. I' am aware, however, that considerable structural variations are possible and the apparatus still be desirable, but as these variations will no doubt be readily understood by those skilled in the `art to which this invention relates, I have not attempted to illustrate or describe the same herein.

Having thus described my invention, what I claim as new and desire to secure by Iletters Patent is:
